Application filed July 2, 1910. Serial No. 570,183.

To all whom it may concern:

Be it known that I, JAMES PHALI, of 11 Blandford Place, Seaham Harbour,Durham, England, merchant and engineer, have invented new and usefulImprovements in Acetylene-Lamps; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part hereof.

This invention relates to acetylene genera tors for automobile, cycleand other lamps and lanterns of the kind in which the generating chambercontaining the calcium carbid is capable of being readily attached to ordetached from the body portion of the lamp comprising the waterreservoir, burner, and other adjacent and necessary parts.

-My invention has for its objects to improve and simplify theconstruction of lamps of this kind and to provide a lamp which may bereadily charged or emptied of spent carbid without (in the case of acycle lamp for example) dismounting from the machine.

In accordance with my invention the generator consists of a circular orother shaped vessel fitted with female mechanisms, one for the waterinlet, and one for the gas outlet. These are fitted together or formedin one and fit into a male mechanism in the lamp and are provided withcircular rubber junction pieces for producing air tight connectionsbetween the gas outlet and the water inlet. Each is adapted to fit intothe other. The female portion of the mechanism is attached to the carbidcontainer or generator, and is pressed up into position by means of alever which produces a gas and water tight connection by means of therubber junction pieces, on the male mechanism of the lamp. The generatorcan be released and taken out at any time by pressing back the lever anda new charged generator can be inserted. The generator can also beconverted into a -temporary acetylene candle by inserting a male piecemechanism similar to that in the lamp with burner attached, and placinga small quantity of water in the generator. For motor lamps two or moregenerators can be used simultaneously, or they can be released instantlyand be used as a candle or be replaced by new charges. And in order thatmy invention may be fully understood, I will proceed to describe samewith reference to the accompanying drawings and figures and letters ofreference marked thereon.

Figure 1 is a sectional elevation of the generator. Fig. 2 is a plan ofthe same. Fig. 3 is an elevation (partly in section) of the lamp showingthe generator detached. Fig. 4 is a plan of the same, partly in sectionthrough line D. D. Fig. 3, showing the lever released. Fig. 5 is a partsectional elevation of the lamp showing the generator fixed and lockedin position, and Fig. 6 is a plan of the upper partof the lamp togetherwith its anti-vibration mechanism.

a is the female orifice for conveying the water to the bottom of thegenerator to at tack the carbid.

b is the female portion of the gas outlet through perforations.

c are notches for inserting the male piece for the burner 20, when usedas a candle, also for the cap 11 to produce an air tight joint toprevent decomposition of the carbid before being used.

c is the male orifice for outlet of gas to the burner.

f is the male. orifice for conveying the water from the reservoir to thebottom of the generator.

9 and h are the circular rubber junction pieces for producing air tightconnections between the male and the female orifices, when the generatoris in position.

Referring particularly to Figs. 1 and 5, A is the generator and 1 is aslit cylinder with a disk attached at its lower end, and placed insidethe generator for the carbid to rest on. 2 is a second disk placedwithin the cylinder and resting on the top of the carbid to keep thesame in position. 3 is a coiled spring attached to the disk 2 to keep itpressed down on the carbid. rubber packings for insuring air tightjoints between the reservoir is and the gas chamber Z leading to theburner w. The parts 0 and p are screwed and serve to render the bottompart of the lamp detachable from the reservoir. 1c is the reservoir withexit orifice. The reservoir 7: is provided with a filling orifice 9closed by a screwed cap 92 with air inlet hole 1), and fitted with aball or clack stopper, to prevent the escape of gas should there be anexcessive flow through the valve outlet, when the water is low in thereservoir. s is the valve screwed at the bottom for regulating the watersupply to the generator. The upper portion is provided with an indexpointer t which moves radially around an index disk u with a collar uati and j are tached. A portion of the collar a is re moved to form astop for the pointer t so as to limit the inflow of water passing intothe generator, and prevent any excess of gas being generated. as is acircular draft screen screwed on to the gas burner socket which fits into the lamp front. 4 is an inverted dome casing inclosing the lowermechanism of the lever 6. 5 is the lever press. 7 shows the dome pieceinverted to serve as a lampstand when the lamp is detached. 8 aresprings for the lever press 5. 9 indicates (see Fig. 6) theanti-vibration mechanism attached to the lamp bracket which mech anismconsists of the screwed rod and nut 12, and the spring 13 inclosed in acasing marked 14. w is the stop tap for regulating the supply of gas tothe burner, and. .2 is a semi-circular guide in which the genera tor isplaced.

What I claim as my invention and desire to receive by Letters Patentis 1. A lamp comprising a water reservoir, a casing secured to the lowerportion of said reservoir a platform hinged to the lower portion of saidcasing, an abutment shoulder formed near the rear portion of the bottomof said platform, a lever slidably engaging the under surface of thebottom of said platform, said abutment preventing said lever fromswinging beyond said platform, and a spring normally holding saidplatform in aidepressed position.

2. A lamp comprising a body portion having a water reservoir in itsupper portion and a gas chamber in its lower portion, a casing connectedwith the lower portion of said gas chamber, a gas pipe passing from saidchamber into said casing, a carbid receptacle provided with an openingthrough which said gas pipe passes, a gasket placed upon said pipebetween said carbid reservoir, and the bottom of said gas chamber, ahinged platform supporting said carbid reservoir, a spring normallyholding said platform in a lowered position, and means for raising saidplatform to clamp said gasket.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES PHALP.
